Breez has introduced Glow, a free and open-source progressive web app designed to let users send stablecoins from their Bitcoin balance. In a press release shared with Bitcoin Magazine, the company said Glow was developed with Bitcoin Spark and is meant to give users a simpler payments experience while giving developers tools to build on Bitcoin without handling the hardest infrastructure pieces themselves.
According to Breez, its SDK manages asset exchange in the background and supports Lightning payments through an integration with Spark. The company said in the release, “Glow is a Bitcoin app for everyone.” Users can access the app through both the Apple and Android app stores.
Glow departs from the seed phrase backup flow that many Bitcoin wallets introduce to new users. Instead, it uses the Passkey standard, which the article describes as having been engineered and promoted by major Silicon Valley technology companies. Breez said that even with that design change, Glow still offers self-custody and cryptographic control over funds in an auditable software package.
The app is released under an MIT license and is structured as a progressive web app, which means developers can inspect the code, break it apart, and add features as they see fit while using the Breez API and SDK.
Beyond Passkey login, Glow includes full support for native Lightning payments. It supports sending and receiving through customizable Lightning addresses that resemble email addresses, such as BM@breez.tips.
Glow was first deployed to a Bitcoiner user base. Through Breez’s partnership with Flashnet, the app can currently send USDT and USDC across most networks and blockchains, with the value drawn from the user’s Bitcoin balance.
The app also comes with onramps from launch. Users can buy bitcoin instantly through Cash App and MoonPay, which the Breez SDK connects to through their APIs. The article says sats arrive in seconds.
Glow includes contacts integration as well, allowing users to save friends’ Lightning addresses as contacts. That removes the need to deal directly with public keys and Lightning invoices and makes the experience look more like a mainstream payments app.
Users can also swap their BTC holdings into USD value when they want to avoid Bitcoin volatility. The press release says they earn sats while doing so.
Glow’s stablecoin is USDB, with the “B” standing for Bitcoin. The article says the token is issued by Brale Inc., which is licensed as a money services business in more than 45 states and says it complies with GENIUS Act standards. The quoted description reads: “Regulated & fully backed Issued by Brale, a U.S. regulated entity, and 100% backed by T-bills, cash, and cash equivalents”.
The report adds that there appears to be no way to verify Brale’s compliance with the GENIUS Act at this stage because the regulations are still being implemented and do not take effect until 2027.
What stands out about USDB, according to the article, is that it is a Bitcoin-native stablecoin deployed through the Spark protocol and compatible with the Lightning Network. That setup puts stablecoin functionality onto Bitcoin rails.
A Spark announcement published earlier this year said USDB holders can earn up to 6% APY, with the yield sourced from the profits of Flashnet’s DeFi exchange.
Breez said this mix of partnerships and technology means that “Bitcoin has finally crossed a threshold.” The company also said the user experience behind Glow is now fully available to developers as a software development kit, something the article describes as unimaginable in traditional finance.
